| 摘 要： | 目的]测定鱼腥草中重金属As、Hg以及666、DDT农药残留的含量,比较不同鱼腥草资源间在相同栽培条件下对其积累的差异。方法]采用海光AFS-3000型双道原子荧光光度计测定As和Hg含量;采用岛津GC-9A型气相色谱仪,按GB/T14551-2003测定666和DDT的含量。结果]鱼腥草幼嫩地上部分中As平均含量为0.161mg/kg,Hg平均含量为0.004mg/kg,地下部分中两者的平均含量分别为0.130和0.0025mg/kg;仅小部分材料中检出痕量δ-666。结论]鱼腥草资源间对As、Hg以及666、DDT积累的差异不显著;根据国标规定,鱼腥草中As、Hg以及666、DDT的含量均低于限量。
